GATE.

SPECIFICATION forming part of Letters Patent No. 353,682, dated December7, 18 86.

' Application filed August 11, 1886.

To all whom it may concern.-

Be it known that I, SYLvEsTER LYMAN ING- HAM, a citizen of the UnitedStates, residing at Granville, in the county of Licking and State ofOhio, have invented a new and useful Improvement in Gates, of which thefollowing is a specification.

My invention relates to improvements in gates; and it consists in thepeculiar construction and combination of devices that will be more fullyset forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a side elevation of a gateembodying my improvements. Fig. 2 is a similar view of the same, showingthe gate in an elevated position. Fig. 3 is a horizontal section takenon the line as x of Fig. 1.

A represents the post to which the gate is hinged, and 13 represents thepost against which the gate closes. The gate is composed of the endbars, 0, which are connected by means of rails D, the said rails beingpivoted at their ends to the bars 0. Near the center of the gate, and onopposite sides of the rails D, is a pair of vertical bars, E, the saidbars being pivoted to the said rails by means of pivotal bolts F.

G represents a pair of pawls or brace-arms, which are pivoted at theirlower ends to the lower rail, 0, near the inner end of the gate. Theupper ends of the said pawls or brace-arms engage recesses or notches H,which are made in the rear sides of the vertical bars E. The said pawlsor brace-arms are connected together by means of a bolt, I, which isadapted to engage a recess or notch, K, that is made in one of the barsor rails D near the rear end thereof.

The operation of my invention is asfollows: As shown in Fig. 1, theupper ends of the pawls or bracearnis engage notches near the upper endsof the bars E. If it be desired to raise the outer end of the gate, soas to support the same in an inclined position, in order to clear asnow-drift or to permit the passage of small stock under the gate, theupper ends of the pawls are caused to engage lower notches or recessesin the rear sides of the bars E. \Vhen the gate is raised to its highestpoint, the bolt I, which connects the pawls or brace- 'them forsimultaneous operation, and the bolt arms D, catches in the recess ornotch K in one Serial No. 210,627. No model.)

of the rails D, as shown in Fig. 2. The boltI connects the pivotedbraces or pawls at an intermediate point of their length, so as to adaptis arranged between two adjacent panels or bars of the gate, so thattheupward movement of the pawls or braces is limited. When the free endsof the gate-panels are elevated to their highest point, the bolt entersthe notch or recess in one of the gate-bars to more effectually preventthe free ends of the pawls or braces from becoming disengaged from theteeth, and thereby more effectually prevent the gate from being loweredwhen it strikes an object or is struck by a passing animal.

A gate thus constructed is cheap and simple, and very strong anddurable, and cannot sag.

I am aware of Patent No. 59,196 for gates, which employs two verticalend pieces or uprights, a series of horizontal bars pivotally connectedat their extremities to the said uprights, the upper bar havingaseriesof notches in its upper edge, and inclined braces pivoted at their lowerends to one of the gate-bars and connected at their upper ends byatransverse pin, which is adapted to enter one of the series of notchesin the upper bar to hold the gate at any desired elevation.

I am also aware of Patents Nos. 47,994 an 77,251, in which a swinginggate is provided with a vertical ceutralnotched bar that is connected tothe horizontal bars of the gate,which in turn are pivoted at theirextremities to the vertical end stiles, and a pivoted inclined baradapted to engage one of a series of notches in the rear side of thesaid vertical central bar.

In myimproved gate I employa pair of vertical central bars, which arepivoted to the horizontal bars of the gate and provided with a series ofnotches in their rear sides, one of the middle bars of the gate beingprovided with anotchinits upperside at apoint thereon some distance inrear of the verticalnotched central bar, and a pair of pawls located onopposite sides of the gate-bars and pivoted thereto at their lower ends,the said pawls being adapted to engage the teeth or notches of thevertical central bars at their free ends, and connected at anintermediate point of their length by a transverse pin or bolt, which isadapted to enter the notch in the middle bar IOU As an improvement ingates, the combina tion of the vertical end bars, the horizontal railspivoted thereto at their extremities, the vertical bars E, arranged onopposite sides of the rails or panels to which they are pivoted andbetween the end bars, and having aseries of notches or teeth in theirrear sides, one of.

the middle horizontal bars of the gate being provided with a notch, K,in its upper side and at a point thereon in rear of the bars E,

the inclined braces or pawls arranged on opposite sides of thehorizontal bars, to which they are pivoted at their lower ends andadapted to engage the teeth or notches in the bars E at their upperends, and abolt, 1, connecting the said braces'or pawls at anintermediate point of their length for simultaneous adjustment, andarranged above the horizontal bar in which the notch K is formed,andadapted to fit in the said notch when the gate the pawls againstdisplacement, substantially as described, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
